Biochemistry

lipid peroxidation

Biology; Biochemistry

The oxidation of polyunsaturated fatty acid side chains, initiated by a free radical such as the hydroxyl radical (OH ), to form a relatively stable carbon free radical, which reacts further with ...

epitope

Biology; Biochemistry

The antigenic determinant; i.e. that part of an antigen to which an antibody is directed; it defines the specificity of the antigen and consequently binds to the receptor on a T-cell or to the ...

An activation mechanism for matrix metalloproteinase family zymogens (named in reference to the zipper-type mechanism), in which the thiol group of a cysteine residue in the N-terminal propart binds ...

cysteine switch

Biology; Biochemistry

informational RNA (iRNA)

Biology; Biochemistry

Essentially, intronic sequences of hnRNA, for which an evolutionary function has been proposed: by a mechanism analogous to the SELEX procedure, and in the absence of any conservative selective ...

nuclear receptor

Biology; Biochemistry

A nuclear protein that allows regulation of gene expression by a lipophilic effector molecule, such as a steroid or thyroid hormone, eicosanoid, retinoid or ecdysone. When the effector molecule is ...

analytical ultracentrifugation

Biology; Biochemistry

A technique of very-high-speed centrifugation that sediments soluble macromolecules and characterizes them according to their rate of sedimentation (sedimentation-velocity ultracentrifugation) or the ...
